I doubt the Nikon TC will work on the lens.
You can try the Kenko, but i won't recommend using a 2X TC on the 28-300mm
you lose alot of light (not sure if the camera will still AF at 300mm) and it'll degrade your IQ alot, given that the 28-300 isn't a very sharp lens to begin with.
you might want to consider the Kenko 1.4x instead.

Both tc with all zoom f2.8 lenses, images going to be soft unless stop down to above f8. Both t. Are for primes only.

If I remember right, the Nikon TC will physically not fit on to the lens. The front tabs on the TC will interfere with the back element of the lens. Check before you buy.
Having said that I believe it is a bad idea to fit a TC on that lens in the first place due the light fall off and IQ degradation.

TCs are best to be used with fast lenses. Your lens should be sharp enough to take the degradation of the 2x TC such that it produces reasonable sharp images even if used. Not all lenses are designed to be used with TCs, especially slower lenses.
